STOVE.

SPECIFICATION forming part of Letters latent No. 273,005, dated February 27, 1883.

Application filed February 20, 1882. (No model.)

To all whom it may concern:

Be it known that I, Mrorranr. G. ARMOUR, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and usefulImprovements in Stoves, which are set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of a stove embodying my improvements; Fig. 2, a longitudinal section of the same on the line a: a: of Fig. 1; Fig. 3, a plan section of the same on the line 3 y of Fig. 2; Fig. 4, a transverse section of the same on the line 22 of,Fig.2; Fig. 5,afront elevation of the stove on a small scale; Fig. 6, a detail view of the stove-top, showing an arran gement of the covering-plates by which the heat is all directed to one of the vessel-openings; Fig. 7, a detail section taken on the line '12 o ofFig. 6, showing the position of the damper-flanges of the covering-plates Fig. 8, a detail .longitudiual section of the upper part of the stove, showing the. damper-flange of one of the covering-plates placed between the tops of the two chimneys to positively keep separate the respective combustion-currents arising therefrom Fig. 9, a detail perspective view of one of the covering-plates with its damperfiange; Fig. 10, a plan view of the lamp, and Fig. 11 a transverse section of the upper part of the lamp, showing the draft-passages and deflecting'plates.

My invention relates to stoves in which oil or gas is the fuel used.

My invention consists, first, of a stove provided with a chamber containing various constituent parts of acombustion apparatus, which parts are separable from each other and from the rest of the stove; second, of details of construction facilitating the adjustment of these separable parts; third, of means for preventing a precipitate flow ofair to the burners; and, fourth, of means for directing and preserving the combustion-current.

In the drawings, A represents an oven heated by radiation. B is a lamp-chamber sepa rated from said oven by a partition-plate, G, and from the chimney-chamber F by a plate, D, the latter plate resting v removably upon cleats d,secured to the former and to the outer 1 wall of the stove, and being guided in sliding in and out by fitting closely between the partition G and said outer wall. E is a plate held apart from and secured to the plate D by the rods e.

Depending from the plate D are the cones Gr, and above, between it and the plate E, are adjusted the chimneys F, which slide in and out between the guidesf, and for which openings are provided in the plate It will be seen from the above that the cones and their respective chimneys form lines, and that the plates Dand E, connected by the rods 0, form a chimney frame, which readily slides into and out of place by the means just specified as adapted for the plate D. The cones reach down'to the level of the air-box K of thelamp K, as shown, and have end apertures, which admit of the entrance under them of the burners H' (which are the upper ends of the wicktubes) when the lamp is made to slide in under the cones, and which are closed, when the lamp reaches its proper place under the cones, by the upright studs or plates J, rising from the top of the lamp, and of such size and shape as to enter and closely fill said end apertures. The sliding of the lamp is directed by the guides 13 and '5.

As the chimneys and chimueyframe are within the chimney-chamber F, the door L is provided, which opens to admit of the insertion and removal of said chimneys and chimney-frame. This door L is provided with mica windows, 1, and opposite these are similar ones in the chimneys for the purpose of observing the condition of combustion and for the emission of light.

L is the oven-door.

The air-box K is supported at a distance above the oil-reservoirk on pedestals or standards in order to keep the oil-reservoir cool. The air-box is provided with draft-deflecting plates each of which, with a plate, 70 forms an air-passage. The air-box is also provided with plates is and it, which also form air-passages. All of these plates within the air-box extend in the direction of the long dimension of the cones and burners entirely across the air box. In the transverse direction, however, the plates k and k do not quite reach the ,rated with holes 11, all as shown, for the purwick-tubes, thus leaving each wick-tube sur- I rounded by an orifice, through which air can approach the flame from all sides of the wick-tubes; and the deflectin g-plates It at their curved ends do not quite reach to the outer wall of the air-box, thus leaving an air-orifice, k Below this orifice k is an orifice, it, in the wall of the air-box. The plate k has orifices k and immediately under these is an orifice, 7c, in the bottom of the air-box. The end of the plate 7a is curved, as shown, in order that when a sudden gust of wind enters the orifice 7; it will pass in beyond the orifice it return above its inward path until it strikes the curved end of the plate 7c, and be deflected by said curved end against and into the incoming current, the result of which collision is that an eddy is created, the collision of the two currents forming a resultant current flowing away from rather than toward the orifice 7G6, and ultimately traversing the eddying path just described for the gust when'first entering the box. Precipitation in the approach to the burners of so much of the air as, notwithstanding these precautions, enters the orifice 70 is still further impeded by the sharp angles which must be encountered by the draft thereafter, as shown in the drawings. The air entering through the orifice k is likewise impeded by the tortuousuess of its course. The courses of the drafts through the air-box are shown by arrows in the drawings.

Above the oven and chimney-chamber is a chamber, M, open on top and at each end. This chamber is covered when in use by one or more of the covering-plates N, O, and 1?. Each of these plates N U P has a depending flange, n, on one side, as shown in Fig. 9, which may be termed a damper-flange, and which is set a little back from the edge of the plate to allow the latter to rest on the parallel rabbeted tops m of the vertical sides of the chamber M. The plates N and 0 have vessel openings and covers Q, and the plate P has grooves 2 across its upper face, the upper edges of which grooves are higher than the nppersurfaces of the other coveringplates and than the tops of the vertical sides ot'the chamber M, and the bottoms of which grooves are perfopose (which it will serve in some arrangements of the covering-plates) of providing an escape for the products of combustion in case of the accidental closing of all other outlets, the upper edges of the grooves being higher than other parts adjacent to the plate Pin order to afford an exit for the combustion-current between such adjacent parts and any cookingvessel accidentally. allowed to cover all or nearly all the perforations through the bottoms of the grooves. V

The operation of my invention so far as it has not already been specified is as follows: The chimneys, alone or with the chimneyframe, may be removed from their position in the stove by simply opening the door L. The lamp may be removed without opening the door L or removing either the chimney-frame or chimneys, though, when desirable, both the chimneys and the chimney-frame may be removed as one piece with the lamp. The covering-plates, being square, can each be set on the stove in any one of four positions, thus rendering possible a variety of positions of the damper-flanges. Thus, in ordinary use, the covering-plates will frequently be set on with the flanges at the back side of the-stove, as shown in Fig. 4, where they are inoperative, leaving a free passage entirely through the chamber M, from each end of which the products of combustion will ordinarily be discharged; but when it is-desired to positively divide, or rather keep separate. the draft arising from one chimney from that arising from the other, (as may be necessary in case of strong drafts tending to enter the end of the chamber M,) oneof the covering-plates is raised and turned around so as to drop its flange between the tops of the chimneys, it being understood that all the damper-flanges are of such a length and depth as, when thus used, to extend entirely across the chamber M both laterally and vertically. This disposition of the covering-plates and damper-flanges is shown in Fig. 8, where the plate 0 has its damperflange across the chamber M. Again, it may sometimes be desired to direct the currents from both chimneys through the vessel-opening of a single covering-plate. In such case one of the covering-plates is removed and the other two plates are placed with their flanges across the chamber M, as shown in Fig. 7, both chimney-tops being between the two damperflanges. By making the rabbeted tops of the sides of the chamber M parallel the positions of the covering-plates may, both as to their" flanges and as to the chamber M, be readily varied. The lamp, chimney frame, chimneys, and cones are removable without disturbing the stove proper, this being accomplished by supporting the latter independently of the former by means of the walls of their containing-chamber. By making the cones below the plate D the chimneyscan be supported by said plate, and can be removed therefrom without interference from the cones projecting up into said chimneys.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oil or gas stove, a removable chimney-support, in combination with a chimney adapted to slide horizontally in and out from the support, substantially as and for the purpose described.

2. in an oil or gas stove, an outer casing, in combination with a separate horizontal plate resting on ways arranged within the casing, and with separate chimneys resting in ways on the plate, the casing being provided with a doorway large enough to allow the passage of the plate and chimneys, substantially as and for the purpose described.

3. In an oil-stove,-the plate D, having the cones of the'burners depending from it, so as to be entirely below it, and'having aperturesv registering with the cones, substantially as and for the purpose described.

4. In an oil or gas stove, the plate D, cones entirely below the same, and chimneys resting upon and removable from the same, combined and operating substantially as set forth.

5. In an oil or gas stove, flues provided with apertures to receive the burners, and a lamp provided with studs for closing said apertures, combined and operating substantially as set forth.
